Optronics MC95 Series Clearance Marker Light Dimensions

Sonically Sealed, Waterproof Trailer Light

The waterproof construction of this light makes it ideal for use on trailers that may be submerged, like a boat trailer. The housing and lens are sonically sealed together to create a single unit, which means that water will not get into the light and damage the diodes or circuit board.

P2-Rated Lights

Diagram of light spread for P2 rated light

A P2-rated light produces a 45-degree angle of light to either side of its centerline for a total of 90 degrees of coverage. This beam pattern can be seen straight on, but it cannot be seen clearly from the side. So this type of light can be used as either a side marker light or a clearance light, but it cannot function as both. If you need both functions, then you must install 2 separate lights on your trailer - one as a front or rear clearance light and one as a side marker light.

Average Customer Rating:  4.9 out of 5 stars   (61 Customer Reviews)

2-1/16" x 1-1/16" Rectangle. Waterproof, incandescent trailer light serves as a clearance or side marker light when properly mounted. Durable stainless steel base. Stud mount to trailer. 1-Wire design. P2 Rated.


Bought this light to replace one that was broken when a deer ran into my boat and trailer. It looks identical to the one used on my Ranger trailer. I made minor modifications to make it plug into the existing wiring harness.
I have been using Etrailer for years due to the great customer service.


These single post, one wire marker lights are getting hard to find at auto stores and big box stores. And if you do, they're wildly overpriced.
I haven't installed them yet but they appear to be identical to the blown out ones on my trailer. They're not LEDs, they're inexpensively made, but I don't need to drill more holes in my fenders to use them and the price is low.
They were delivered on time and well packaged.


Fantastic OEM equipment the marker lights for my trailer were top shelf...


Delivery was quick and I received the correct part for my trailer.


Straight forward install. Product meet my expectations.


Exactly what I needed, and quick shippi ng.


Great product


As described. Exactly what I need to replace the one that broke.


Ordered these lights as part of a complete trailer lighting overhaul. Bought the waterproof cases for the rear and after a little epoxy where the wires enter the case, all is waterprrof and up and running.

Easy to mount and connect to the main wires. After all the work, I can put the boat in and not have to fix a light or take anything apart to fix a lighting issue. Best use of a day over my vacation, outside of fishing.


This is the perfect replacement light for my boat trailer. This is the first time I made a puchase from Their selection is extensive and at a nice price. For a notice it was easy for me to use their site to find the replacement lights I needed. It was received in less than 5 days at my doorstep and everything I ordered was there. All the tips and installation videos are invaluable to me. This is much more than a great place to purchase lights, it's a DIY'ers learning site.


every thing was perfect all done trailer looks great.
i will b ordering one more accessorie
just wish i didnt have to pay a shipping fee but other than that great
prices etc...


perfect the product was for my brothers trailer it all works looks great
-- comment by: fernando - 02/14/2014


First, you're product (fender for trailer) was the correct item. It was sized right and extremely easy to add to my trailer as was the running light. The quality was fine and ----I have to tell you-- you saved me at least half. Thanks


etrailer always have original replacement parts. Even with shipping the prices are equal to Amazon prime prices. Good job etrailer. Always excellent communications thru the whole transaction.


The clip lights I bought were very reasonably priced and they work great! Also the lights were shipped in a very fast time, even with the standard shipping! Thanks etrailer!!!


This light is an exact replacement for the clearance markers on my Venture trailer. Very nice light.


My package arrived quickly and just as advertised...great deal. Big improvement to my boat trailer. I will make more purchases in the future.


Perfect replacement for my boat trailer. Carefully packaged and delivered promptly.
Thanks etrailer!!!


This is the same product that originally came on you boat trailer. It is easy to install and works great!


Haven't installed it yet, but this is the light that I was having trouble finding. I've ordered from etrailer before and I will order from them again.... Thanks


From order entry to delivery was excellent, informative and quick. Products were exactly (pretty standard stuff) what was ordered, and everything worked as expected.


Perfect match thanks to the pics on the site, had an order number within a couple hours of placing it at 10.30 at night and received it in 3 days. OUTSTANDING!! THANX


Got the item on Sat. Due to the weather on Sun. installed it on Mon. Easy installation.


Very good product and was a nice fit where my old ones were removed. Nothing to drill fit right in. Looks great !


These lights look great and are extremely easy to install. Very happy with the product


Good quality and still working well a year later.

  • Can the Optronics Clearance Light part # MC95AB Install on Trailer that Has 2 Wires
    The Optronics Clearance Light part # MC95AB would still work well for you. This light grounds through the mounting hardware so what you would need to do is take the ground wire on your trailer's wiring and run it to the mounting stud of the light and then run the wire of the light to the power wire on the trailer.

  • Replacement OptronicsMC-95 Red and Amber Lights
    We do offer the red and amber Optronics lights. The red is part # MC95RB and the amber is part # MC95AB.

  • Adding Side Marker Lights to Open Utility Trailer
    Yes, side marker lights can be added to your open utility trailer. When adding these lights you will just need to make sure that you do not exceed the amp rating of the trailer wiring harness. In an effort to add lights to your trailer without exceeding the amp rating of the trailer wiring harness, I recommend going with an LED light like the Double Bullseye LED Trailer Clearance and Side Marker Light, # MCL45AB. This light draws a mere 0.087amps at 12.8 volts.

  • Which Trailer Lights will Fit a Fulton Fender F008595?
    As I couldn't tell if the lights in the picture are LED or incandescent, I included with both options. For incandescent lights, you will need the Optronics Mini Trailer Clearance or Side Marker Light - Submersible - Incandescent # MC95RB for the red light and # MC95AB for the amber light. For LED lights, you will need the Optronics LED Clearance or Side Marker Light - Submersible - 3 Diodes - Rectangle # MCL95RB for the red light and # MCL95AB for the amber light. All of these lights...

  • How to Wire Trailer Light # MC95AB to Trailer with Two Wires
    The trailer light part # MC95AB that you referenced has a single power wire and grounds through the mounting hardware. Since your trailer currently grounds with a wire you can just run the wire to the stud and you'd be set. For butt connectors we have the # 05731-5 for a 5 pack.

  • How to Wire a Mid-Trailer Turn Signal on a 24 Ft Haulmark Trailer Towed with a 2005 GMC Yukon XL
    If the lights at the middle of your trailer are connected to the turn signal circuit then they will go solid when the brake lights are activated since trailers are wired with a two wire system. There really is no easy fix for this problem that I am aware of. One option is to wire a connector with an extra circuit, if your Yukon has separate yellow turn signals at the rear, I believe most do, you could use a 5-Way connector set like the 5-Way Flat Trailer Wiring Kit, item # HM47890, and...

  • Parts Needed to Convert a Trailer Side Marker Light to Running Light and Turn Signal
    On trailers, the turn signals and brake lights are combined. You could install the Vehicle to Vehicle Taillight Converter, # 118158, but your side marker lights must be dual function lights, like our Optronics Oval LED Turn Signal and Parking Light, # STL78AB. If your current running lights have only one wire, not including a ground wire, to power the light, it is not a dual function light. I have attached a link to all of our dual function amber LED lights for you to check out. The Vehicle...

  • Amber Trailer Blinker/Running Light Recommendation for Use on an Older Truck
    We don't have exactly what you said you need, but the closest thing we have would be the Miro-Flex, Waterproof, Rectangular, LED # STL35AB. This is an LED amber light you could use that has dual intensity so that it can be used for a blinker and running lights. Only thing is that this is much bigger at 5-5/16" L x 3-7/16" W x 2-5/16 D. For a harness to plug into the light you would want # A47PB and then for a grommet part # A33GB.
